Hi all!
Our application now has following
looks:
Following changes were made:
1. SnapToGuides - now it uses method
getEditorGuidePositions - this allows for the rulers that are offset relative to
the editor origin (i.e., in our case - the top ruler is centered in editor), so
the ruler provider provides conversation between ruler coordinates and the
editor coordinates. Default implementation implies that these coordinates are
same.
2. DragGuidePolicy, RulerDragTracker,
GuideEditPart, now works with the IRulerEditPart interface - this allows
to provide your own from the ground implementation of the ruler edit parts
(vertical compound rulers, etc.)
3. RulerEditPart was splited into the public
IRulerEditPart interface and GEF-private default implementation
(RulerEditPartImpl)
4. RulerFigure was changed in following
ways:
1. IOrientableFigure interface -
as layouts, itc. want to know the ruler orientation and implementing the
interface perfectly enables developer to provide his own figures that look
totally different (compound vertical ruler in our project.
2. AbstractRulerFigure - it's
base class that allows drawing marks, etc. - makes it easy to create custom
ruler figures (in our project all rulers are custom, i.e. they don't have border
on their own)
3. RulerFigureImpl - default
ruler figure same in functionality as original RulerFigure
5. RulerComposite now allows to provide another
EditPartFactory - so the new rulers are plugged here.
Another rework was done to change to the Unit class
- it was needed as our project has need for the custom units that were
incompatible with the old GEF units.
Changes in other classes were only connected to the
class hierarchies refactorings. In the logic sample diff file you can see the
amount of the changes that were needed to perform to change to new
rulers.
Sorry, if the formatting/comments is not fully
correct - I've checked the eclipse.org but was unable to see the strict enough
recomendations. I do hope that these changes will be merged to the GEF CVS -
because I need to release my code to our project.
I will provide support/enhancments/bugfixes to this
ruler implementation (I mean, all GEF Bugzilla requests that will be
ruler-related).
Best regards,
Eugene
